Step 1: Upgrade to the Required firmware

Ensure that the phone is running on the required firmware by 3CX. In case the device needs manual updating download the latest distributed required firmware by 3CX here. Read how to check what firmware the phones are running on and how to upgrade them in this guide: How to manual upgrade Yealink IP phones.

Step 2: Factory Reset the IP Phone

Before provisioning the IP phone, the phone must be brought back to factory defaults in case the device has residual settings of a previous configuration. To reset the device read our How to Factory Reset Yealink phones.

Step 3: Provision the phone

There are several methods to provision a phone:

Plug & Play - For phones on the local LAN or behind the 3CX SBC.

RPS - For phones on remote networks that will connect directly to 3CX and use STUN.

You can make sure that the extension is ready to be configured via RPS by checking the “Event Log” from the dashboard:

If the message appears as a “Warning” follow the instructions outlined in the message and use the Manual Link Provisioning method outlined here.

The phone is now ready to be provisioned - you can boot up the phone anywhere in the world with access to the internet.

The phone will prompt for username and a password: Enter the extension number as username, then press the DOWN arrow to get to the password input field and enter the voicemail pin as the password.

Note: Ensure that the input mode is set to digits (green box).

Step 4: Extended Phone Configuration

IP phones can be tweaked to match the user’s needs. Those might be skipped if they are not desired and the phone will be rolled out in a default configuration. Also they can be altered at a later stage and changes applied via the Management Console → Phones → Select Device → Re-Provision :
